COMETS is designed to be a participatory project between academic researchers, policy makers, and relevant stakeholders.

COMETS contributes to a cost-effective fossil free energy and transport sector by 2050, by understanding the impact on the energy system from 1) the transport sector, 2) consumer preferences and behavior regarding transportation, and 3) planning of cities and transport infrastructure.

First, COMETS will develop a new modeling framework that links TIMES-DK with Lands Trafik Modellen run by DTU Transport. The goal is to develop an energy system modeling framework beyond state of the art, integrating transport and energy system analyses.

Second, COMETS will analyze the environmental and economic impacts on the future energy system from an increasingly renewable-based and system-integrated transport sector.

Third, COMETS will produce a plan for de-carbonizing the Danish Energy System that highlights when transport and fuel infrastructure need to be developed.


Foreseen Output

Scientific output: COMETS will link two modeling frameworks to improve modeling of transport in scenarios. The LTM model will be soft-linked to TIMES-DK. COMETS will develop a new type of transport module in TIMES that more accurately represents transport technologies, modal shift, and infrastructure investments. This will lead to the development of a model framework allowing for analyses of the influence on transport patterns and modal shifts from investments in infrastructure, and for how different policy measures (taxes, road pricing systems, regulation, etc.) impact transport demand. Furthermore, novel insight in stakeholder involvement in energy planning will be gained.

End-user tools: The modeling framework and linking tool will be open source and a light version of the tool will be developed, which can be used in workshops and run by stakeholders.

Policy analysis: COMETS will provide holistic/cross disciplinary analysis of policies and means to reach/promote the 100% renewable target for Denmark in 2050 with focus on solutions for the transport sector.

Societal ownership: Societal actors will be involved in workshops and similar activities during the project, connected to consortia meetings. This will distribute ownership of the outcomes by promoting discussion and debate concerning scenarios, by establishing consensus on system decisions, and by promoting participatory policy analysis.
